-
-**1**:
-
-DNS servers are refactored for better performance and scalability.
-
-See [DNS server](/configuration/dns/server/).
-
-For migration, see [Migrate to new DNS server formats](/migration/#migrate-to-new-dns-servers).
-
-Compatibility for old formats will be removed in sing-box 1.14.0.
-
-**2**:
-
-Legacy `outbound` DNS rules are deprecated
-and can be replaced by the new `domain_resolver` option.
-
-See [Dial Fields](/configuration/shared/dial/#domain_resolver) and
-[Route](/configuration/route/#default_domain_resolver).
-
-For migration,
-see [Migrate outbound DNS rule items to domain resolver](/migration/#migrate-outbound-dns-rule-items-to-domain-resolver).
-
-**3**:
-
-See [Route Action](/configuration/route/rule_action/#tls_fragment) and [TLS](/configuration/shared/tls/).
-
-**4**:
-
-New certificate options allow you to manage the default list of trusted X509 CA certificates.
-
-For the system certificate list, fixed Go not reading Android trusted certificates correctly.
-
-You can also use the Mozilla Included List instead, or add trusted certificates yourself.
-
-See [Certificate](/configuration/certificate/).
-
-**5**:
-
-See [Tailscale](/configuration/endpoint/tailscale/).
-
-**6**:
-
-Due to maintenance difficulties, sing-box 1.12.0 requires at least Go 1.23 to compile.
-
-For Windows 7 users, legacy binaries now continue to compile with Go 1.23 and patches from [MetaCubeX/go](https://github.com/MetaCubeX/go).
-
-**7**:
-
-The new AnyTLS protocol claims to mitigate TLS proxy traffic characteristics and comes with a new multiplexing scheme.
-
-See [AnyTLS Inbound](/configuration/inbound/anytls/) and [AnyTLS Outbound](/configuration/outbound/anytls/).
-
-**8**:
-
-See [TLS](/configuration/shared/tls).
-
-The build tag `with_ech` is no longer needed and has been removed.
-
-**9**:
-
-See [Protocol Sniff](/configuration/route/sniff/).
-
-**10**:
-
-See [ShadowTLS](/configuration/inbound/shadowtls/#wildcard_sni).
-
-**11**:
-
-Now `auto_redirect` fixes compatibility issues between tun and Docker bridge networks,
-see [Tun](/configuration/inbound/tun/#auto_redirect).
-
-**12**:
-
-You can now set `bind_interface`, `routing_mark` and `reuse_addr` in Listen Fields.
-
-See [Listen Fields](/configuration/shared/listen/).
-
-**13**:
-
-DERP service is a Tailscale DERP server, similar to [derper](https://pkg.go.dev/tailscale.com/cmd/derper).
-
-See [DERP Service](/configuration/service/derp/).
-
-**14**:
-
-Resolved service is a fake systemd-resolved DBUS service to receive DNS settings from other programs
-(e.g. NetworkManager) and provide DNS resolution.
-
-See [Resolved Service](/configuration/service/resolved/) and [Resolved DNS Server](/configuration/dns/server/resolved/).
-
-**15**:
-
-SSM API service is a RESTful API server for managing Shadowsocks servers.
-
-See [SSM API Service](/configuration/service/ssm-api/).
-
-**16**:
-
-TUN now implements SideStore's StosVPN.
-
-See [Tun](/configuration/inbound/tun/#loopback_address).
-
-**17**:
-
-We have significantly improved the performance of tun inbound on Apple platforms, especially in the gVisor stack.
-
-The following data was tested using [tun_bench](https://github.com/SagerNet/sing-box/blob/dev-next/cmd/internal/tun_bench/main.go) on M4 MacBook pro.
